Problem

Web viewer gradually gets slower over a period of time, and also simple tasks take considerable time. Gradually the web viewer gets so slow that it stops responding. Eventually a restart of IIS is triggered which brings back web viewer to normal behaviour. Process repeats.

Solution

For sites with a large database and a lot of visitors, caches can build up and consume a lot of memory.

  • Check if the IIS worker process consumes a lot of memory.

  • A high memory consumption is not a problem, provided that there is sufficient memory on the server. Check available memory on the server.

  • Also verify that the application is running in 64 bit mode (and not 32 bit) in IIS. If running in 32 bit mode also a fairly low memory consumption can be too high and trigger bad behaviour.
